Usually cam sensors go bad from normal wear. After a long period of time, like most things, they start to see an end to their long life, and need to be replaced. As far as damaging a sensor yourself, it can vary from oil spills (not using a funnel, and accidentally spilling oil onto the sensor), and water can also damage a sensor, so try not to open your hood when it's pouring unless it's necessary.
Engine sensors will only "go bad" from environmental effects. Lack of oil causes excessive heat. Heat can cause cam sensor failure
No
It could possibly, if it causes the computer to go into a limp home mode.
Thermocycling.
Hope this will help it happend to me. It was my cam sensor and the dealer fixed it for free.
It's Japanese. That's how.
The seat sensor is probably going bad. Have it checked for codes, possible rear axle sensor bad.
If you have a 4g63 motor a common problem is crankwalk, this will damage or break off the sensor.
The cam sensor is the pickup plate under the distributor cap.
Most likely a bad sensor/relay
In my case, it was a crank shaft sensor that went out, causing the cam sensor to go out, which may have led to the killing of the fuel pump. $200 later, hopefully it fixes it.
I think you mean the "Crank Sensor" since it's magnetic (The cam sensor is optical). Not sure how you could install the balancer incorrectly since it is "Keyed" onto the crankshaft. If the "Key" was missing you could get it installed other than at the right timing location but even then the metal tabs on the back of the balancer should still go through the sensor's slot ok. Unless the sensor is not adjusted correctly. Usually the crank sensor (Hall Effect) isn't effected by anything other than physical contact from something. I've seen them destroyed because someone used bolts that were other than OEM that were to long to install the crankshaft pulley onto the balancer That causes the metal tab (Sensor Flag) ring on the back of the balancer to be pushed into the sensor. TommyTrouble The cam sensor IS magenetic in these cars. BUT installing the balencer on the CRANK would not cause damage to the cam sensor, it would damage the crank sensor which is a hall effect. The cam sensor/magnet usually malfunctions on these cars. The cam sensor itself it easy to change, but the magnet is not.
